Mujahid said that the meaning of «مهين‏» is weak, feeble (or insignificant), referring to a man's semen. The meaning of «ضللنا‏» is "we are destroyed." Ibn Abbas (may Allah be pleased with them both) said «جرز» is the land where there is very little rain, from which no benefit is derived (or hard and dry land). The meaning of «يهد‏» is "we explain."
